语谱图的实现过程，对于初学者有很大的帮助(Spectrogram of the realization of the process, very helpful for beginners )

统一混沌系统的simulink文件可以自己改变参数(unified chaotic system Simulink documents themselves can change the parameters)

energy detector for spectrum sensing for cognitive radio

本程序主要是应用到无线传感器网络目标定位与追踪中，通过利用MUSIC算法来测量接受信号的波达方向角DOA，然后进一步定位与追踪。(This procedure is mainly applied to wireless sensor networks, targeting and tracking, the MUSIC algorithm is used to measure the signal direction of arrival angle DOA, then locate and track.)

此函数主要用欧式距离法和maha法实现图像分割。简单实用。(Image segmentation)

用matlab编程实现车牌字符的识别，在识别中运用了模板匹配的方法(Matlab programming realize license plate character recognition, the recognition using a template matching method )

matlab 中用Bisection方法求解一元多次方程，是一种很好的算法。但收敛速度比较慢，是线性收敛(matlab using Bisection method for solving multiple equations one yuan, is a good algorithm. But convergence is slow, linear convergence)

该程序是灰度图像的坐标变换，用于二维图像平移，放大。(The program is a grayscale image of the coordinate transformation for two-dimensional image translation, zoom.)

利用PLSI算法自动对一个文档集进行聚类，需要调节聚类的维度K值，从而得到最大的likelihood(PLSI automatically using an algorithm for clustering document set needs to be adjusted to the dimension value of K clusters, to obtain the maximum likelihood)
